Abstract

Devices and systems control energy usage in accordance with instructions from a head end system. A device may be instructed to cease energy consumption. Another device may allow users to override some instructions. Messages may be provided to users to request the cessation of energy consumption; the users may, but need not comply.

Claims

1. A system comprising:

a head end server;

a mesh gate in communication with the head end server;

a plurality of target devices, wherein each of the target devices is in communication with the mesh gate and each target device belongs to one of a plurality of target device classes;

a request interface in communication with the head end server receiving an instruction to control energy use of target devices belonging to a selected target device class; and

a scheduler in communication with the head end server, the scheduler receiving the instruction and identifying one or more target devices belonging to the selected target device classes;

wherein the head end server creates a message for the mesh gate in communication with the identified target devices via the mesh gate to limit energy use of the identified target devices, and transmits the message to the mesh gate; and

wherein the mesh gate, upon receiving the message, authenticates the message, removes message headers, and provides a table request to each of the identified target devices to control energy use of the identified target devices.

2. The system of claim 1, wherein the mesh gate comprises a NAN-WAN gate.

3. The system of claim 1, wherein a message includes a command to limit energy usage, and the command is overridden.

4. The system of claim 1, wherein the message includes a command to limit energy usage, and the command is not overridden.

5. The system of claim 1 further comprising a home gateway in communication with the mesh gate and the plurality of target devices.

6. The system of claim 5, wherein the table request is provided to each of the identified target devices via the home gateway.

7. A method comprising:

receiving, by a request interface, a request to control energy use of a class of target devices;

providing, by the request interface, the request to a scheduler in communication with a head end server;

identifying, by the scheduler, one or more target devices belonging to the target device class;

creating, by the head end server, a message for the identified target devices said message including a request to control energy use of the identified target devices;

providing, by the head end server, the message to a mesh gate in communication with the one or more target devices upon receiving the message at the mesh gate, authenticating the message, removing message headers, and providing a table request to each of the identified target devices to control energy use of the identified target devices.

8. The method of claim 7, wherein the request is received via the simple object access protocol (SOAP).

9. The method of claim 7, wherein the message is provided as a table request is formatted for an ANSI C12.19 table.

10. The method of claim 7, wherein the message is formatted to ANSI C12.22 format.
